Rollover into the growth-fault-initiated trap formation occurred between about 1.2 Ma and the present. Fault movement occurred during each lowstand of sea level when differential loading from shelf-edge deltaic sedimentation and consequent salt withdrawal destabilized the upper slope system.<ref name=ch04r8>Armentrout, J., M., 1993, Relative seal-level variations and fault-salt response: offshore Texas examples: Proceedings, Gulf Coast Section SEPM 14th Annual Research Conference, p. 1–7.</ref> Given the sea-level fluctuation cycles documented within the East Breaks 160-161 minibasin<ref name=ch04r10>Armentrout, J., M., Clement, J., F., 1990, Biostratigraphic calibration of depositional cycles: a case study in High Island–Galveston–East Breaks areas, offshore Texas: Proceedings, Gulf Coast Section SEPM 11th Annual Research Conference, p. 21–51.</ref><ref name=ch04r8 /> at least five and potentially nine lowstand events may have caused episodic movement of the north-bounding growth fault of the East Breaks 160-161 field ([[:File:Sedimentary-basin-analysis fig4-31.png|Figure 1]], nine cycles between 1.2 Ma and the present).
